Hi, I want to make a date format for MMM-YYYY (Jan-2015) for use in some listboxes and still keep the other M/D/YYYY date format for use in field values. Can someone provide me the line to add below for MMM-YYYY date format that wouldn't replace or conflict with the default date format? Previously, I'd been doing weird concatenate month() year() functions in script and would like to quit that.

Thanks for the array of insights, Rob. It looks like I had slightly the wrong question/approach, and that the OrderDate part of the Date function was the gap in my knowledge I needed to fill in. (Someone else chimed in with that part after you too, and I'll tag them for helpful answer points.)
